摘要：A method for supplying a selected quantity of gas to the mold of an injectionmolding machine utilizes two high pressure gas bottles which are connected through apressure reducing valve to a piston reservoir for receiving a quality of the gas. The pistonreservoir is hydraulically powered to supply the gas to a further piston reservoir having asmaller volume which is connected through a valve to the mold. The second pistonreservoir is also hydraulically powered for supplying a selected quality of gas under avariable pressure to the mold. Gas from the mold is recycled to both reservoirs in steps.
